User Modeling, Adaptation, and Personalization 22nd International Conference, UMAP 2014 Aalborg, Denmark, July 7-11, 2014 Proceedings 13 Volume Editors Vania Dimitrova University of Leeds, UK E-mail: Preface The 22nd International Conference on User Modeling, Adaptation, and Person- alization (UMAP2014) was held in Aalborg, Denmark, during 7–11 July, 2014. UMAP is the premier international conference for researchers and practitioners working on systems that adapt to their individual users or to groups of users. UMAP is the successor of the biennial User Modeling (UM) and Adaptive Hy- permedia and Adaptive Web-based Systems (AH) conferences that were merged in 2009. It is organized under the auspices of User Modeling Inc. The confer- ence spans a wide scope of topics related to user modeling, adaptation, and personalization. UMAP2014 submissions were invited from a broad range of issues faced by modern user adaptive systems, covering the following key areas: UMAP in the so- cial era; UMAP in the era of big data; UMAP in the era of pervasive computing; infrastructures, architectures, and methodologies; human factors and models; personal and societal issues. The conference included high-quality peer-reviewed papers solicited from two areas: research and experience. The research papers present substantive new research results on user modeling, adaptation, and/or personalization. The experience papers present innovative use of user modeling, adaptation, and personalization, exploring the benefits and challenges of apply- ing user modeling techniques and adaptation technology in real-life applications and contexts. Leading researchers acted as area chairs who provided strategic help in se- lecting the Program Committee and conducting the review process. The in- ternational Program Committee consisted of 101 leading members of the user modeling and adaptive hypermedia communities as well as highly promising young researchers. They were assisted by 40 additional reviewers. There were 146 submissions, each submission received three reviews; a meta-reviewer facil- itated consensus achievement when needed. In all, 23 submissions (16%) were accepted for long presentation at the conference, and another 19 papers were ac- cepted for short presentation at the conference, i.e., the overall acceptance rate was 29%. Papers addressed well-established as well as emerging topics in user modeling, adaptation, and personalization. Among these are: large-scale per- sonalization, adaptation and recommendation; personalization for individuals, groups and populations; modeling individuals, groups, and communities; Web dynamics and personalization; adaptive Web-based systems; context awareness; social recommendations; user experience; user awareness and control; affective aspects; UMAP underpinning by psychology models; privacy, perceived security and trust; behavior change and persuasion. Three distinguished researchers gave plenary invited talks on related topics, illustrating prospective directions for the field. Elizabeth Churchill, Director of Human Computer Interaction at eBay Research Labs in San Jose, California, VI Preface USA, presented a framework for thinking about people-centered systems design. Kaj Grønbæk, Professor at the University of Aarhus, Denmark, and heading the Ubiquitous Computing and Interaction Research Group at the Department of Computer Science, gave an overview of methods being developed for mobile sensing and understanding user behavior in urban contexts. Gregory D. Abowd, Regents’ and Distinguished Professor in the School of Interactive Computing at Georgia Tech, USA, and leading the Ubicomp Research Group, presented how a concrete application domain, such as autism and related developmental disabilities, could present a wide variety of opportunities for computing research. The conference also included a doctoral consortium that provided an oppor- tunity for doctoral students to explore and develop their research interests under the guidance of a panel of 18 distinguished research faculty. This track received 11 submissions of which five were accepted as full presentations and another three were accepted as poster presentations. The poster and demo session of the conference received 27 submissions, from which 17 were accepted. The UMAP2014 program included the following workshops: – Personalized Multilingual Information Access, organized by Ben Steichen, Maristella Agosti, S´eamus Lawless, and Vincent Wade – Personalizing Search - From Search Engines to Exploratory Search Systems, organized by Tuukka Ruotsalo, Giulio Jacucci, Peter Brusilovsky, Samuel Kaski, and Oswald Barral – News Recommendation and Analytics, organized by Jon Atle Gulla, Ville ¨ ¨ Ollikainen, Nafiseh Shabib, and Ozlem Ozgo¨bek – Personalization Approaches in Learning Environments, organized by Milos Kravcik, Olga C. Santos, and Jesu´s G. Boticario – Personalization in eGovernment Services, Data and Applications, organized by Nikos Loutas, Fedelucio Narducci, Adegboyega Ojo, Matteo Palmonari, C´ecile Paris, and Giovanni Semeraro – Emotions and Personality in Personalized Services, organized by Marko Tkalˇciˇc, Berardina De Carolis, Marco de Gemmis, Ante Odi´c, and Andrej Koˇsir – Workshop on UMAP Projects Synergy, organized by Dhaval Thakker, Oliver Brdiczka, and Christoph Trattner. UMAP2014 also included the following tutorials: ˙ – User Affect and Sentiment Modelling by Bjo¨rn W. Schuller – Social Information Access by Peter Brusilovsky – Personalization for Behavior Change by Julita Vassileva and Judith Masthoff We would like to acknowledge the excellent work and great help from the UMAP2014 Organizing Committee listed herein. We would like to acknowl- edge Marwan Al-Tawil’s help with compiling the proceedings of UMAP 2014 and thank him for his efforts. We also gratefully acknowledge our sponsors who helped us with funding and organizational expertise: User Modeling Inc., U.S. Preface VII National Science Foundation, Microsoft Research, Springer, the Chen Family Foundation, and Aalborg City. Finally, we want to acknowledge the use of Easy- Chair for the management of the review process.
